' Renewed June 9, 1934 31 Claims. (Cl. 105-234) This invention relates .to railway rolling stock and especially to certain improvements in locomotive tenders for stoker fired locomotives, and it also appertains to improvements in a stoker fuel conveyor for use particularly with the improved locomotive tender.

t has heretofore been the practice to mount the stoker fuel conveyor or its trough portion in a. separate compartment formed on the tender between the fuel and water compartments. The fuel conveyor in such installations is driven from gearing at its rearward end disposed at the back of the trough compartment. This arrangement and contruction materially reduces the space available for Water and complicates the fabrication and maintenance of the tender and of the stoker conveyor.

An object of this invention is to obviate these difficulties and disadvantages of'past practice by the provision of a new and improved tender structure and stoker conveyor simplifying fabrica-p tion of the tender and at the same time, affording more space for fuel and Water, and wherein the stoker trough conveyor is driven from its -I forward end exteriorly of theV tender water coma most important factor in the development of new locomotives, and it is highly desirable to obtain the maximum capacity. The design of the tender trucks, bolster and frame determine,

the lowest point for the bottom of the tender. Clearances of the road, such as tunnels, bridges, switch stands, platforms, etc. determine the height and width of the tender. The length is controlled by the physical characteristics, length of turn tables, and the length of stalls in the engine houses. 1 Thus it will be understood the size of the tender is held Within the foregoing well dened limitations. Hence, it is essential all space on the tenderbe utilized to advantage and as much as possible given over to the fuel and Water` compartments.

This invention is directed to, as its principal object, the provision of an improved tender structure including `itoker mechanism constructed to afford maximum fuel and water space.

Referring now to the drawings, Figures 1 to 8, illustrate a preferred form of construction selected for the purpose of best describing the invention. Figure 9 shows a modified form of the invention, but it will be evident that other forms may be employed without departing from the spirit of my invention.

The locomotive tender designated generally at A is formed with a fuel compartment B and a water compartment C, and is provided with a fuel conveyor indicated as a whole at D, which .conveyor forms a functionally integral part of the'tender structure as will presently appear. IIJ represents the tender base or frame which comprises the bottom or base plate II and an upper plate I2 connected by the ribs I3, and extends from one end of the tenderV to the other. The base plate II is solid, but the upper plate I2 has a series of perforations I4, and the ribs I3 are apertured at I5, so that water can circulate from the water compartment freely in the space between the two plates II and I2.

The fuel compartment A is formed by, and separated from the water compartment by partition plates comprising the rear slope sheet I6, the side slope sheets I1 and I 8, and the trough member I9 of the fuel conveyor, which trough member in transverse cross section is formed, preferably, of an inverted A shape with the sidewallsr 20 and 2I thereof forming substantially straight extended wall portions of the side sheets, I 'I and I8. I'hese side sheets and trough sidewalls are securely fastened by riveting, welding orin any suitable manner to form a. water tight joint between the .fuel and water compartments. Likewise at their: i

`together with the lower extended portion of the rear slope sheet serves vas water baiiies. Any suitable or desired number of. such supporting plates may be used as the form` of the tender may require.

As can be seen from Figures 1 and 7 particularly the trough member I 9 is preferably, though not necessarily, provided inthe form of a cast metal integral casting including the centrally and longitudinally apertured cross wall 24 which serves as a floor for the fuel compartment and carries the slidable plates 25 movable longitudinally in the seat portion 26 to provide a-.shiftable opening 21 through which the fuel enters the trough member.

At its forward end the trough member l|9 extends through the water compartment to communicate with a forwardly extending sectional conveyor conduit 30, the rear portion of which is disposed below the trough member and is mounted in a centrally arranged compartment E disposed between the conventionaltender bulkheads 3| and 32. AThe compartment E is formed above the frame I0 and beneath the extended fuel bin oor portion 33. It is bounded at its sides by the bulkheads. Thefront end is open to receive the conveyor conduit and associated mechanism and is closed at its rear portion by the upstanding transverse wall or partition plate 35 which extends laterally between the sidewalls 36 and 31 of the bulkheads, and vertically between the-frame III and the trough member I9. The plate 35 is secured to parts named and these parts together with the side-slope sheets I1 and I8 are arranged in a manner to form a. water tight closure for the water compartment. Figures l and 8 clearly 'l illustrate the compartment E and its relation with the remaining tender structure.

It will be seen from Figures 1 and 5 that a ring deck 40 is positioned below the fuel compartment oor portion 33. The distance between the floor and the deck may be varied as desired to meet particular conditions. In this construction less physical eiort will be yrequired when hand ring is necessary since the reman 'will not be required to stoop when filling the shovel with' fuel.

The trough member I9 built in the tender as contemplated by this invention permits utilization of space for water or fuel heretofore wasted. In the construction shown the passage 4| beneath the trough member communicates with the water compartment C as best shown in Figures l and 'I to provide communicating water space underneath the partition plates and beneath the trough member. Thus it can be seen that the water compartment extends beneath' the fuel trough and all of this space can be used to carry water,

or if desired, the construction may be such that this space canbe utilized to increase both the fuel and water carrying capacity of the tender in any preferred ratio of one to the other.

A novel fuel advancing conveyor system, including the trough member4 I9 heretofore described, and a'drive arrangement peculiarly apcounter v shaft 82.

plicable for use with the improved tender of this inventionl will now be de cribed in detail inasmuch as it is also consid red an important feature of the invention. Only that part of the stoker mechanism that advances fuel forwardly from the. tender is shown and it will be understood that any form or preferred type of the stoker -locomotive unit including distributing means can be used with the tender conveying system 'of this invention. i The trough member I9 is provided at its forward end with a ange 50, which is suitably-secured to the corresponding flange 5I at the rear of the hopper-like casing 52 mounted in the compartment-E. The casing 52 is supported from the 'frame I0 by the legs 53 and 54, which preferably are formed as an integral part of the casing. The upper portion 55 of the casing 52 forms an extension of the trough and is closed at its forward end by a vertical wall 5S forming one of the sidewalls of a gear housing compartment 51, provided with a. removable cover 58. The lower portion 59 of the casing 52 extends forwardly beyond the upper portion 55 forming a conduit 60 terminating in a spherical flange. BI adapted to be received in the vertically split coupling member 62 attached to a forwardly extending conduit 63. The portion 59 of the casing 52 is closed at its rearward end by a. wall 64 forming one of vthe sidewalls of a gear housing compartment 65. The gear housing compartment 65 is provided with a cover plate 56, which is shown in the drawings as being an integral part of the trough, though obviously it may be made a separate part. The upper portion 55 of the casing 52 communicates with the lower portion through the opening 61 in itsv oor. From 'another aspect of the invention the casing 52 may be considered, and is in effect a hopper-like extension of the conduit 60.

In the trough is a rotatable screw 10 extending into .the portion 55 of the casing 52, made up of a plurality of sections suitably connected as by universal joints. Thisscrew is supported inv the split bearing 1I at its rearward end and coupled to the shaft 12 at its forward end. The

use of a plurality of screw sections permits easy\ screw 15. The screw 15 is coupled to the shaftv 16 at its rearward end and flexibly attached at its forward end to the screw 11, as by a universal joint 1a.

The gear driving mechanism for the conveyor system is located at the front end of the tender trough and all gears are in a self-contained casting within the compartment E and entirely with- 12. This shaft carries the gear 89 which engages 'the gear 8| mounted on the forward end of 'the The counter shaft extends rearwardly'beneath and to one side of the screw 10 and mounted on its rearward end is a gear 83 which engages the gear 84. The gear '84 mounted on the shaft 16 in turn engages the gear 85 mounted on the shaft 86. On the same shaft 86 is mounted the gear 81'which engages the gear 88 mounted on the power shaft 89.

The power shaft can be driven from either end from any suitable prime mover such as by a two cylinder double acting reversible steam engine mounted in the locomotive or if preferred, mounted in the tender directly connected with either end of the power shaft. If the Stoker engine is mounted on the tender it would be desirable to enlarge the compartment E by extending it laterally into one of the bulkheads, or extending the compartment further back in the tender. l

In order to protect the trough member I9 from the abrasive action of the screw 10 a removable wear plate 98 is placed 'in the arcuate shaped portion. This eliminates the necessity of replacing the entire trough member because of frictional Wear of the screw and the movement of the fuel.

Referring to Figure 9 a modification is-shown in which a single cast screw 9| is used in the trough member in place of the sectional screw 10, All other parts are the same as heretofore described.

Those familiar with tender construction will readily recognize that this invention provides an improved tender and fuel conveyor so constructed and arranged as to utilize all space practically possible for the supply of fuel and water, and that a tender so constructed-with all the driving parts for the conveyor mounted exteriorly of the water compartment permits increased tender fuel and water capacities -or both in preferred ratios of one to the other.

It is apparent that the trough member may be made either of plates ora cast metal, or that the trough supporting members may be formed inventional form and location of bulkheadsand comprising fuel and water compartments separated by partition plates, a Stoker conveyor extending Within said water compartment and opening upwardly to receive fuel from said fuel compartment, and an alcove exteriorly of said water compartment disposed between said bulkheads to receive stoker drive mechanism.
